  I dont know about the performer saveFile() function but the SGI format
does support 16bit components and if you want to verify that your SGI
image is truely 16bits per component run imginfo on your file and the
line that says "Data type" should say "unsigned short", if it is 8bit
then it will say unsigned char. I know this doesnt answer your question
but at least you know a little more about the SGI format. :)
